Mathematics - Statistics - Measures of Spread - Range and interquartile range - Same Average, Different Spread

Show pairs of datasets with the SAME mean but very different distributions. E.g., Team A scores: {48, 49, 50, 51, 52} vs Team B: {10, 30, 50, 70, 90}. Both average 50! Ask: 'Which team is more consistent?' 'Which team is more unpredictable?' For 4 pairs, the student picks which is more spread out. T
